a. Scientific advancements have led to the ability to detect some hazardous events before they occur, allowing society to plan for them, mitigating their damage.

Scientific advancements helped reduce the impact of hazardous events on society in various ways. As science progress and study hazardous events, it is possible to be able to predict some of them, this allows society to be prepared, at least in theory, and with the knowledge comes the ability to mitigate them, and avoid suffering, economic costs and even loss of lives to the people that are unluckily involved in those types of events. 

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
